I am an Marine Engineer, he my direct line of work deals with water flow and movment, but does it mean I know about turf scrubbers... hell no never even seen one, but I di know alot of people have to low of flow on them also (I have been reading about them) but I do know water flow and pumps, and heaters, and well anything else that is mechanical with out tanks. hmm maybe I should write a book now that I am retired.

Let me guess, you haven't even read the book

So based on the book you read, you are discounting P.R. Escobal's mathematical formulas. Please post your references so we can compare the math. If the author of the book you read had a breakthrough that challenges the industry standards that Escobal has set, then I would love to see how they came to a different conclusion.
